Fig. 6From: Overexpression of P21-activated kinase 4 is associated with poor prognosis in non-small cell lung cancer and promotes migration and invasionLIMK1 overexpression rescued the effects of si-PAK4 on A549 and NCI-H520 cell migration and invasion. A549 or NCI-H520 cells were transiently transfected with Si-PAK4 or LIMK1 or both, and then seeded for migration (a) and invasion assay (b) under at × 40 original magnification.
